btw - I let her borrow my 808 PT all last weekend with a fully wrapped "menthol" carto. Yesterday sh returned it and thanked me for letting her try it out. Guess what? The carto had never been taken out of the wrapper.
You are going through an anger phase and don't realize it. I'm sorry to hear about your brother, that must have been terribly difficult. I have been through similar experiences with family members, one who smoked incessantly after being diagnosed with emphysema while on oxygen. She would turn off the oxygen, smoke, and turn it back on. She finally passed on with a heart rate of 180bpm while on FULL 100% oxygen in intensive care. I was there by her bedside when she died.
Sometimes, we don't realize how love can be overpoweringly smothering. We care so much about someone that we drive them crazy trying to change them. Alienation can be the result. Give your friend time. She has the details and is in denial. Don't drive her further away. Let the message sink in. You've done your part.
